The present invention is described further below in conjunction with accompanying drawing:
Accompanying drawing 1 is principle of the invention figure;
Embodiment:
Therefore the following stated does not limit protection scope of the present invention only for embodying the preferred embodiment of the principle of the invention.
Solar storage battery disclosed by the invention discharges the control circuit of electric energy, circuit comprises storage battery 1, alternating current back-up source 2, one reverser IC (CD4069), comparator IC (LM399), optocoupler is every element Q1 and on-off controller Q2, Q3, battery positive voltage connects a voltage stabilizing element (LM7812) and series resistance R10 connects reverser IC (CD4069) the 1st pin and comparator IC (LM399) the 10th pin, and series resistance R11 connects reverser IC (CD4069) the 4th pin, storage battery 1 negative pole one tunnel serial connection becomes resistance R14, connect reverser IC (CD4069) the 8th pin, and serial connection becomes resistance R15, fixed value resistance R16 connects reverser IC (CD4069) the 11st, 12 pins constitute Schmidt circuit, another road of storage battery 1 negative pole connects reverser IC (CD4069) the 13rd, 14 pin, storage battery 1 negative pole Third Road series resistor R17 is connected with the 13rd pin of reverser IC (CD4069), and by R9 serial connection comparator IC (LM399) the 11st pin, at resistance R 14 series resistor R8 and connect comparator IC (LM399) the 10th pin, resistance R 8, R9 forms a bleeder circuit, for comparator IC (LM399) provides reference voltage; Reverser IC (CD4069) and the external optocoupler of comparator IC (LM399) are every element Q1 and on-off controller Q2, Q3, divide two-way output through drawing the back on R2, the R11, by R3, R4, R5 optocoupler every element Q1 conducting, optocoupler makes the voltage that produces a trigger switch controller Q2 between R6 and the R7 every element Q1 conducting, with on-off controller Q2 conducting, and connect control alternating current back-up source.
Operation principle of the present invention is as follows:
When the voltage of storage battery 1 descends the end during in 21.5V, reverser IC (CD4069) is connected pin with resistance R 17 and is output as 1, two voltage comparators and the reference voltage that are sent among the comparator IC (LM399) compare, comparator IC (LM399) is through resistance R 2, draw the back to divide two-way output on the R11: 1, by resistance R 3, R4, the R5 optocoupler is every element Q1 conducting, optocoupler makes every element Q1 conducting and produces a voltage that triggers optocoupler every element Q2 between resistance R 6 and the resistance R 7, with optocoupler every element Q2 conducting, the operating state of system is for enabling the back-up source state at this moment, if but this moment, system still had commercial power supply, back-up source be with this circuit be off-state, so this moment, this circuit did not provide power supply to system, whole system is for enabling city's electricity condition.2, the second tunnel output is passed to reverser IC (CD4069) after drawing on the resistance R 11, and the not gate of logical CD4069 the inside provides output to R12, R13 respectively and since this moment the CD4069 the inside not gate receives is 1 signal, resistance R 12, R13 are output as 0.Optocoupler is in cut-off state every element Q3.
When the voltage rising of storage battery 1 is higher than 23.5V, reverser IC (CD4069) is connected pin with resistance R 17 and is output as 0, two voltage comparators and the reference voltage that are sent among the comparator IC (LM399) compare, comparator IC (LM399) divides two-way output through drawing the back on resistance R 2, the R11: also be 0 by resistance R 3, R4, R5 output 1,, optocoupler is in cut-off state every element Q1, and optocoupler also is in by shape every element Q2.2, the second tunnel output is passed to reverser IC (CD4069) after drawing on the resistance R 11, the not gate of logical reverser IC (CD4069) the inside provides output to resistance R 12, R13 respectively, because what the not gate of reverser IC this moment (CD4069) the inside was received is 0 signal, R12, R13 are output as 1.Q3 is in conducting state, and what this moment, system enabled is the power supply (promptly enabling sun-generated electric power powers) of storage battery 1.
Above circuit can see and draw, and when at the bottom of the voltage of storage battery 1 during in 21.5V, optocoupler is in conducting and optocoupler is in every element Q2 and ends every element Q2.When the voltage of storage battery 1 rises a little higher than 21.5V, circuit does not overturn at once, optocoupler every element Q2 still keep conducting state and optocoupler every element Q3 also remain off state still, when the voltage rising of storage battery 1 is higher than 23.5V, circuit just overturns, change into optocoupler every element Q2 by and optocoupler every element Q3 conducting.Equally, when the voltage of storage battery 1 was lower than 23.5V slightly, circuit also was not overturn at once, and optocoupler is every element Q2 remain off and optocoupler keeps conducting every element Q3, dropped to when being lower than 21.5V up to the voltage of storage battery 1, and circuit just overturns.That is to say that when the voltage of storage battery 1 was in the state of 21.5V～23.5V, optocoupler was in certain stable operating state every element Q2 and optocoupler every element Q3.
By top control circuit, can make full use of the electric energy of solar energy supply, and can protect the normal use of storage battery 1, setting its voltage that discharges electric energy is 23.5V (adjustable), the voltage that turn-offs the output electric energy is 21.5V (adjustable).Promptly storage battery 1 charging voltage is reached 23.5V when above when photovoltaic panel, the electric energy that control circuit discharges storage battery 1 uses for load; When storage battery 1 is depressurized to 21.5V when following because of the offered load power consumption, control circuit turn-offs storage battery 1 electric energy to be stopped electric.Treating that storage battery 1 is recharged once more reaches 23.5V when above, and control circuit discharges the supply of electrical energy load of storage battery 1 once more to be used, and circulates with this.
